Question

why were farming methods such as chinampas and terraces important?
a. ◯ they increased farmable land and food production
b. ◯ they stopped invasions
c. ◯ they eliminated flooding
d. ◯ they replaced the need for trade

Explanation:

Chinampas (floating gardens) and terraces (stepped farming on slopes) are agricultural techniques. Chinampas create farmable land in wet areas, and terraces make use of hilly/mountainous land for farming. Both increase the amount of land available for agriculture, which in turn boosts food production. Option B is incorrect as they don't stop innovation. Option C is incorrect as they don't eliminate flooding (terraces can reduce erosion and runoff but not eliminate flooding entirely, and chinampas are in water - they don't eliminate flooding). Option D is incorrect as trade is still needed for various resources. So the correct answer is A.

Answer:

A. They increased farmable land and food production
